In urinary tract infections, there may be flocculent or feathery deposits in the urine, which may also appear as cloudy urine. These are due to urinary tract infection, and there are more pus cells in the urine, so the phenomenon of thick urine, or cloudy phenomenon occurs. At the same time, after the infection, the mucous membrane of the urinary tract epithelium is shed more, mixed with white blood cells or tubular type of material, will form flocculent or feathery floating material, and may be accompanied by frequent and urgent urination, burning in the urethra, pain in the urethra and other symptoms. Further urinalysis and culture tests are needed to identify the specific pathogenic bacteria for targeted treatment. Urinary tract infections can also cause bleeding from the mucous membrane of the urinary tract, which can manifest as cloudy flesh-washing urine, or directly as light red urine. When there is more bleeding, even small blood clots can be formed and excreted with the urine.
